Experimental technique for detection of induced gamma emission in transition Te(125m,2) → Te(125m,1) + hν(109.27 keV)

We present a series of experimental details for detecting an induced gamma emission (IGE) in the M4 transition: Te(125m,2) → Te(125m,1) + hν(109.27 keV). First, we studied the lower level non-stability impact on a value of the IGE effect under measurement. Secondly, we offer the best mode for the tellurium-125m,2 preparation in concentration just higher than 1021 atoms per cm3. Thirdly, we studied the IGE measurement effect value depending on the type of solid matrix containing Te(125m,2). Fourthly, we suggest to combine absorbing filters in an effort to separate the gamma radiation 109.27 keV and double-energy quanta 218.54 keV under investigation, from the Bremsstrahlung and other background radiation. In the fifth place, we propose to use the appropriate types of a preamplifier, a detector and other electronic units in order to suppress an instrumental double-energy line 218.54 keV. (authors)
